Analytic Besov functions, pre-Schwarzian derivatives, and integrable Teichmüller spaces

Katsuhiko Matsuzaki, Huaying Wei

We study the embedding of integrable Teichmüller spaces into analytic Besov spaces via pre-Schwarzian derivatives. In contrast to the Bers embedding by Schwarzian derivative…

The real analytic structure of the Teichmüller space of circle diffeomorphisms with Zygmund continuous derivatives

Katsuhiko Matsuzaki

We apply the methods of simultaneous uniformization and composition operators on Besov spaces to the Teichmüller space of circle diffeomorphisms with Zygmund continuous deri…

Simultaneous uniformization of chord-arc curves and BMO Teichmüller space

Katsuhiko Matsuzaki

This article surveys and develops the use of simultaneous uniformization for the study of chord-arc curves in the BMO Teichmüller space. The method of simultaneous uniformization…

The complex structure of the Teichmüller space of circle diffeomorphisms in the Zygmund smooth class II

Katsuhiko Matsuzaki

In our previous paper with the same title, we established the complex Banach manifold structure for the Teichmüller space of circle diffeomorphisms whose derivatives belong to the…

The complex structure of the Teichmüller space of circle diffeomorphisms in the Zygmund smooth class

Katsuhiko Matsuzaki

We provide the complex Banach manifold structure for the Teichmüller space of circle diffeomorphisms whose derivatives are in the Zygmund class. This is done by showing that the S…
